Hyaluronic acid fillers have a satisfactory safety profile.

The authors sought to give guidance on how to minimize the risk and optimize the management of this rare but catastrophic adverse reaction.

A multinational group of experts in cosmetic injectables from multiple disciplines convened to review current best practice and develop updated consensus recommendations for prevention and bedside intervention if visual loss occurs after cosmetic injection of hyaluronic acid filler.
